      1 The following are demonstrations of the runocc.d script.

      5 Here we run it on a single CPU server that is fairly busy,
      6 
      7    # ./runocc.d
      8    
      9         CPU  %runocc
     10           0       86
     11    
     12         CPU  %runocc
     13           0       85
     14    
     15         CPU  %runocc
     16           0       82
     17    ^C

     19 The run queue occupancy is around 85%, meaning most of the time there
     20 are runnable threads queued waiting for CPU.

     24 This script is more interesting on a multi-CPU server,
     25 
     26    # ./runocc.d
     27    
     28         CPU  %runocc
     29           1       16
     30           3       27
     31           0       38
     32           2       75
     33    
     34         CPU  %runocc
     35           0       25
     36           2       41
     37           3       42
     38           1       50
     39    
     40         CPU  %runocc
     41           3        1
     42           0       17
     43           2       26
     44           1       27
     45    
     46         CPU  %runocc
     47           3        2
     48           2        5
     49           0       24
     50           1       25
     51    ^C

     53 Here there was some degree of saturation, especially on CPU 2 to start with.
